I'm surprised they lasted.....it is a known weakness that resulted in a redesign/update. Unfortunately the redesign is not backwards compatible as it requires a different shaft. When the rear half of my driveshaft was replaced, I got the updated bearing for that part..my front shaft is still the old design.
Either way....be glad you didn't need a new shaft, it could put a guy out of business.
Man you guys go thru parts like water...
In Sidney Oh...just delivered...
I refused one to Long Is. which Danthewolf is now running..
